Compatibility
LGA 1851 Core Ultra (Series 2) processors only, such as the Core Ultra 5 225 or Core Ultra 7 265K; 12th to 14th Gen chips will not fit. DDR5 only. B860 supports memory overclocking but not CPU overclocking. Most LGA 1700 coolers fit LGA 1851, but confirm with the cooler maker.
FAQ
Will an i5-14400 or i7-14700K fit?
No. LGA 1851 is for Intel Core Ultra (Series 2) processors; 12th to 14th Gen chips use LGA 1700.
Does it have Wi-Fi and Bluetooth?
Yes. Wi-Fi 6E 2x2 on 2.4/5/6GHz with Bluetooth 5.3, and a Q-Antenna that attaches without tools.
Does it support Gen5 SSDs?
Yes. M.2_1 runs at PCIe 5.0 x4 directly from the CPU. The second slot is PCIe 4.0 x4.
